Variational Inequalities Exceptional Family And Epvi The Error Bounds

In this paper,we introduce a new concept of @- exceptional family for variational inequality with general nonempty closed convex sets. We apply this concept to deal with the existence problems of the solution .Moreover , we discussed the feasibility of nonlinear complementarity problem by another exceptional family.On the other hand,we make use of gap-function to study the error bound for EPVI.
